LM35 Temparature Sensor With Arduino :

Its quite an easy project…

Step 1: Connecting on Breadboard & Code

Connecting on Breadboard & Code

 

Code: 
TMP36 Pin Variables

int sensorPin = 0; //the analog pin the TMP36’s Vout (sense) pin is connected to //the resolution is 10 mV / degree centigrade with a //500 mV offset to allow for negative temperatures /* *

void setup()

{

Serial.begin(9600);

}

void loop()

{

int reading = analogRead(sensorPin); // converting that reading to voltage, for 3.3v arduino use 3.3

float voltage = reading * 5.0;

voltage /= 1024.0; // print out the voltage

Serial.print(voltage);

Serial.println(” volts”); // now print out the temperature

float temperatureC = (voltage – 0.5) * 100 ;

Serial.print(temperatureC);

Serial.println(” degrees C”); // now convert to Fahrenheit

float temperatureF = (temperatureC * 9.0 / 5.0) + 32.0;

Serial.print(temperatureF);

Serial.println(” degrees F”);

delay(1000); //waiting a second

}
